Abstract
The utility model relates to a compression valve, which mainly includes a compression valve stem, a compensating spring, a compensating valve plate and a base, the compression valve stem is arranged at one end of the compensating valve plate, and is sleeved with a three-claw reed and a location-limited plate. The compression valve stem passes through orderly a valve plate, a throttle valve plate, the valve base, the compensating valve plate, the three-claw reed and the location-limited plate, the compression valve stem fixedly connects each parts together at the rotating rivet; a ring groove is arranged on the location-limited plate, the reed on the three-claw reed pushes against on the ring groove. The compensating valve plate of the utility model has a compensating valve plate via hole cooperated with the compression valve stem at the center of the compensating valve plate, and is arranged with waist-shaped grooves uniformly distributed along the circumferential direction. The three-claw reed of the utility model is opened with reed via hole cooperated with the compression valve stem at the center of the three-claw reed, and is arranged with reed claws uniformly distributed along the circumferential direction. The utility model has beneficial effects of that due to the added location-limited plate parts as well as the three-claw reed matched with the location-limited plate which replaces the cone spring, the compensating function can be effectively improved so as to avoid compensating valve plate opening infinitely.
Description
Technical field
The utility model relates to a kind of valving, especially a kind of compression valve.
Background technique
Originally be applied to the compression valve in the vibration damper, as shown in Figure 1, this compression valve mainly comprises compression valve rod 1, counterbalance spring 2, compensation valve block 3, valve seat 4, throttle valve plate 5, valve block 6 and packing ring 7, between the base of compensation valve block 3 and compression valve rod 1, be provided with counterbalance spring 2, the deficiency of its structure is: owing to adopted counterbalance spring 2, when flow velocity was big, compensation valve block 3 can produce unlimited phenomenon of opening.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of compression valve of improving compensate function is provided.
The utility model solves the technological scheme that its technical problem adopts: this compression valve, mainly comprise compression valve rod, counterbalance spring, compensation valve block and valve seat, the compression valve rod is in a side of compensation valve block, be set with three-jaw reed and limiting board, the compression valve rod passes valve block, throttle valve plate, valve seat, compensation valve block, three-jaw reed and limiting board successively and each parts is fixed together revolving riveting place; Limiting board is provided with circular groove, and the reed pawl on the three-jaw reed is pressed on the circular groove.
The technological scheme that its technical problem that solves the utility model adopts can also be further perfect.
Compensation valve block described in the utility model has in the centre and compresses compensation valve block through hole that valve rod matches, and along the circumferential direction is provided with equally distributed kidney slot.
Three-jaw reed described in the utility model has in the centre and compresses the reed through hole that valve rod matches, and along the circumferential direction is provided with equally distributed reed pawl.
Limiting board described in the utility model has in the centre and compresses the limiting board through hole that valve rod matches, and along the circumferential direction is provided with equally distributed limiting board slotted eye.
The effect that the utility model is useful is: owing to increased the limiting board parts, and change volute spring into cooperate three-jaw reed with limiting board, therefore can effectively improve compensate function, infinitely open to avoid compensating valve block.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 2, this compression valve, mainly comprise compression valve rod 1, counterbalance spring 2, compensation valve block 3 and valve seat 4, compression valve rod 1 is in a side of compensation valve block 3, be set with three-jaw reed 9 and limiting board 8, compression valve rod 1 passes valve block 6, throttle valve plate 5, valve seat 4, compensation valve block 3, three-jaw reed 9 and limiting board 8 successively and each parts is fixed together revolving riveting place 10; Limiting board 8 is provided with circular groove 8-3, and the reed pawl 9-2 on the three-jaw reed 9 is pressed on the circular groove 8-3.
As shown in figures 1 and 3, described compensation valve block 3 has in the centre and compresses compensation valve block through hole 3-1 that valve rod 1 matches, and along the circumferential direction is provided with equally distributed kidney slot 3-2.
As shown in Figure 1 and Figure 4, described three-jaw reed 9 has in the centre and compresses the reed through hole 9-1 that valve rod 1 matches, and along the circumferential direction is provided with equally distributed reed pawl 9-2.
As shown in Figure 5 and Figure 6, described limiting board 8 has in the centre and compresses the limiting board through hole 8-1 that valve rod 1 matches, and along the circumferential direction is provided with equally distributed limiting board slotted eye 8-2.
Working principle: during low speed, pressure oil flows out by kidney slot 3-2, the limiting board slotted eye 8-2 of the through hole in the middle of throttle valve plate 5, the valve seat 4, compensation valve block 3; During middling speed, pressure oil will compensate valve block 3 and back down by the looping pit of valve seat 4 two sides, and flow out the sideshake between counterbalance spring 2 and compensation valve block 3, and by the elastic force of control three-jaw reed 9, can control great pressure can be to opening compensation valve block 3; Because the position-limiting action of limiting board 8 has been controlled compensation valve block 3 and can only have been moved, thereby controlled the unlimited unlatching of compensation valve block 3 effectively in certain scope.
